112. Heavy Ion Targets

Roger Bangerter

13/08/2012, 13:55

Invited talk

Roger O. Bangerter Lawrence Berkeley National Laboratory Berkeley, California, 94720, USA During the last 38 years researchers have suggested and evaluated a large number of target designs for heavy ion inertial fusion. These target designs fall into a number of general categories including: 1. Direct ignition (or fast ignition) designs originally suggested by A. W. Maschke 2. ...

129. A look at past heavy ion target designs

Max Tabak (Lawrence Livermore National Laboratory)

13/08/2012, 14:20

Invited talk

Max Tabak Lawrence Livermore National Laboratory In this talk I shall describe the distributed radiator target and its several variants—the hybrid design and the close-coupled target. This target was used in the Robust Point Design reactor scenario requiring about 6MJ of 3.5-4GeV Pb ions and yielding about 400 MJ. Several design issues shall be discussed: why a radiation driven target;...

134. The X-target: a high-gain and robust target design for HIF

Enrique Henestroza

13/08/2012, 14:45

Invited talk

E. Henestroza and B.G. Logan Lawrence Berkeley National Laboratory, Berkeley, California, 94720, USA A new inertial-fusion target configuration, the X-target, using one-sided axial illumination has been explored [1]. This class of target uses annular and solid-profile heavy ion beams to compress and ignite deuterium-tritium (DT) fuel that fills the interior of metal cases that have...

138. Tamped Heavy Ion Targets

Matt Terry (Los Alamos National Laboratory)

13/08/2012, 15:50

Invited talk

The deeply penetrating nature of heavy ion beams makes for unique opportunities in the design of ICF targets. We describe a class of targets that take advantage the long range and Bragg peak-like deposition profile of to drive an implosion contained within a dense, high-Z tamper. The The targets consist of spherical shells of DT ice, plastic, and a thin gold tamper. The design uses two...

116. Impact Ignition Design under Axi-symmetric Illumination System

M. Murakami (Institute of Laser Enginering)

13/08/2012, 16:15

Invited talk

M. Murakami Institute of Laser Enginering, Osaka University Suita, Osaka 565-0871, Japan In impact ignition scheme, a portion of the fuel (the impactor) is accelerated to a super-high velocity beyond 108 cm/s, compressed by spherical convergence, and collided with a precompressed main fuel. The collision generates strong shock waves in both the impactor and the main fuel. Since the...

130. Fusion Ignition Simulations using a Particle Code

Richard More (Lawrence Livermore National Laboratory)

13/08/2012, 16:40

Invited talk

Richard M. More (1,2) (1) HIFS-VNL, Lawrence Berkeley National Laboratory, 1 Cyclotron Road, Berkeley, CA (2) Lawrence Livermore National Laboratory, East Avenue, Livermore, CA A molecular dynamics (MD) particle simulation code has been developed to study inertial fusion ignition physics including effects of a non-Maxwellian ion velocity distribution. 10,000 DT ions at...

137. Two stage focusing for FAIR and HIAF

B. Logan

13/08/2012, 17:05

Invited talk

B. G. Logan Key elements of a 44 page MathCAD study will be presented for two-stage longitudinal drift compression and final focusing of 200 GeV heavy ions using a combination of a dE/dx wedge for large (20-30%) tilt generation close to an X-target, followed by a shaped powered lithium lens for final achromatic focus. Key feasibility aspects of this concept include how wedge-shaped beam...
